Customer Reviews
Detailed feedback on my order
I placed an order for a Fuel System Combo, which included a K-Series Fuel Rail and an E85 Fuel Line Kit. The website was easy to navigate when ordering, and the product descriptions were clear, especially regarding compatibility. Shipping took about five business days to reach me in California, which was within their estimated timeframe. The packaging was robust, and all components arrived undamaged. I had a quick question about installation for the E85 line, so I used their online chat support. The representative was knowledgeable and provided helpful guidance. The quality of the fuel rail felt solid, and the PTFE Fuel Line was exactly as described, making the installation straightforward. Everything fit perfectly on my engine. Overall, a positive experience and I'm happy with the performance gains.
Quick shipping, good parts
Ordered some AN Fittings. They arrived fast. Parts seem high quality. Fitment was perfect. No issues with my order.
Pretty good, got my stuff fast
I ordered a Walbro Fuel Pump last week, just needed to replace my old one. It shipped out pretty quick, got to me in about 4 days, which was nice. Everything was in the box and looked like it should. No complaints here, it was a straightforward order and everything worked out fine. I'd probably buy from them again if I need something else.
Awesome Fuel Pressure Regulator!
I just got my new Adjustable Fuel Pressure Regulator from JBtuned and it's fantastic! The quality is top-notch, and it was so easy to install. My engine is running so much smoother now. I'm definitely coming back for more parts soon and telling all my car friends about this place. What a great find!
Good value on Fuel Line Kit
I was looking to upgrade my K-Series fuel system and compared a few sites. JBtuned had a Fuel Line Kit that was just what I needed, and the price was really competitive. I found a deal for free shipping, which made it an even better value overall. It felt like I got a solid product without overspending, so that was great.
Ktuned Community Discussion
Share tips, ask questions & help fellow shoppers save more
I'm looking at some Injector Dynamics. Are these guaranteed genuine or like, knock-offs people try to pass off?
any black friday sales usually pretty good at JBtuned? trying to time a big purchase.
Hey, thinking of grabbing a full fuel system for my K-swap. How long does shipping usually take to California?
Thinking of going with JBtuned for my fuel system, but Hybrid Racing also has some good stuff. Any thoughts on how they compare?
Wondering about returns. What if something doesn't fit right or I change my mind after ordering?
Can you stack coupon codes at JBtuned? Got a clearance item and a newsletter sign-up code.
What's the deal with their military discount? Do you just email them or is there a code?
Are their fuel lines actually E85 compatible? Don't want to mess up my setup later on.
